Description

Polygon endoporus shaping handle of a knife

Technical field

The utility model relates to the apparatus field that adopts cutting process processing inner polygon hole on metal material, specifically a kind of polygon endoporus shaping handle of a knife.

Background technology

At present, on metal material, process the polygon endoporus usually, as hexagon, four limits etc., adopt cold extrusion, Re Chong, or the method processing of dashing of electric pulse and artificial drift, need particular device and frock, the part processing dimensional accuracy is uncontrolled, because the punching press internal stress is big, some part is as the hexagon endoporus, after punching press, leave serious residual stress, use in important events to produce phenomenon such as break, cause serious consequence.Versatility is poor, more incompatible process requirements at complex parts and many specifications of small lot product.

The utility model content

For solving above problems, the utility model provides a kind of endoporus of polygon efficiently shaping handle of a knife,

The technical scheme that realizes the foregoing invention purpose is as follows:

Polygon endoporus shaping handle of a knife, comprise a shell, one end of shell connects eccentric main handle, the other end is for being provided with polygon cutter one end, be provided with a self-aligning bearing in the shell, the outer ring of self-aligning bearing cooperates with the inner surface of shell, the inner ring of self-aligning bearing matches with a swinging axle, swinging axle is provided with a shaft block ring near eccentric main handle one end, be provided with a pad that is placed on the swinging axle between shaft block ring and the self-aligning bearing, an end relative with the shaft block ring end is set of described swinging axle axially has the installing hole of polygon cutter, is positioned at installing hole portion and radially is provided with a lock screw on swinging axle.

The utlity model has the versatility height, be suitable for part is carried out batch machining, accuracy height, yield rate advantages of higher.

Description of drawings

Fig. 1 cuts open figure and corresponding processing parts figure for the structure partial of an embodiment of the present utility model;

Fig. 2 cuts open figure and corresponding processing parts figure for the structure partial of another embodiment of the present utility model.

The number in the figure explanation:

01, eccentric main handle; 02, shaft block ring; 03, adjusts pad; 04, shell; 05, self-aligning bearing (radial ball bearing); 06, swinging axle; 07, lock-screw; 08, polygon cutter; 09, part to be processed; 10, Digit Control Machine Tool taper shank.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As depicted in figs. 1 and 2, eccentric main handle 01, by screw thread be connected with shell 04, shell 04 and self-aligning bearing 05 outer ring cooperate, because shell 04 is connected with eccentric main handle 01 screw-threaded coupling, the main handle 01 of off-centre and shell 04 and the associating of self-aligning bearing 05 outer ring is as a whole, and self-aligning bearing 05 inner ring and swinging axle 06 cooperate, and the thickness of adjusting pad 03 by reconditioning is with shaft block ring 02 control axial motion, polygon cutter 08 is installed in the swinging axle 06 end face installing hole, with lock-screw 07 locking.

The embodiment of Fig. 1 statement and Fig. 2 different being of embodiment of explaining wherein, Fig. 1 is used for machine tool, and Fig. 2 is used for Digit Control Machine Tool.

Method of work 1, the rotation of polygon endoporus shaping handle of a knife, part to be processed 09 does not rotate.

Process on the drilling machine:

The inscribed circle bottom outlet d of prefabricated required polygon endoporus on part to be processed, and in aperture D*90 ° chamfering

The main handle 01 of off-centre is packed in the drill press spindle hole, main axis rotation drives the whole simultaneously rotation of eccentric main handle 01 and shell 04 and self-aligning bearing 05 outer ring, this moment, polygon cutter 08 contacted with workpiece, and did not rotate, and made swinging axle 06 and self-aligning bearing 05 inner ring not rotate simultaneously.

As seen from the figure at angle＜a〉and eccentric throw＜S effect down, main axis rotation, polygon cutter 08 and swinging axle 06 and self-aligning bearing 05 inner ring are done the periodicity circle swing within the specific limits and are not rotated.Feeding this moment is done propelling cutting feeding with the polygon cutter along the axis direction of hole in piece part, processes required polygonal hole.

Method 2, the part to be processed rotation, polygon endoporus shaping handle of a knife does not rotate.

Engine lathe processing:

The inscribed circle bottom outlet d of prefabricated required polygon endoporus on part to be processed, and in aperture D*90 ° chamfering.

The main handle 01 of off-centre is packed in the lathe tailstock hole, parts fixation is on spindle chuck, the rotation of main axis rotation part, the tailstock feeding, polygonal cutter head 08 rotates synchronously with part contact zones movable pendulum moving axis 06 and self-aligning bearing 05 inner ring, because eccentric main handle 01 and shell 04 and self-aligning bearing 05 outer ring are an integral body, eccentric main handle 01 does not rotate in lathe tailstock, and main shaft and part and polygon cutter head 08, swinging axle 06 and this moment of the rotation synchronously of self-aligning bearing 05 inner ring.As seen from the figure at angle＜a〉and eccentric throw＜S the effect under, polygon cutter head 08, swinging axle 06 and self-aligning bearing 05 inner ring are done periodically within the specific limits, and circle swing does not rotate toward each other, the polygon cutter is done along the axis direction of hole in piece part and is advanced the cutting feeding, processes required polygonal hole.

By above operation principle, as can be known with original axially greatly resistance to cutting,, great resistance to cutting disperseed to be transformed into do on the polygon cutter periodically that circle swing advances cutting by efficient polygon endoporus shaping handle of a knife, reach the reduction resistance to cutting, finish the processing of polygon endoporus.

Claims

1. polygon endoporus shaping handle of a knife, it is characterized by: comprise a shell, one end of shell connects eccentric main handle, the other end is for being provided with polygon cutter one end, be provided with a self-aligning bearing in the shell, the outer ring of self-aligning bearing cooperates with the inner surface of shell, the inner ring of self-aligning bearing matches with a swinging axle, swinging axle is provided with a shaft block ring near eccentric main handle one end, be provided with a pad that is placed on the swinging axle between shaft block ring and the self-aligning bearing, an end relative with the shaft block ring end is set of described swinging axle axially has the installing hole of polygon cutter, is positioned at installing hole portion and radially is provided with a lock screw on swinging axle.
